Almost every signal within a facility touches a router. They are the heart of a station’s infrastructure. Therefore, when choosing a new router, flexibility is key, especially as facilities convert from analog to digital and high definition. Here’s a smattering of what’s on the digital video router market these days.
FOR-A will be introducing the “Clean Switch” series, the first in its new series of HD routing switchers, at NAB. “We will introduce [the] Clean Switch CS-HD series at NAB this year,” said Hiro Tanoue, sales manager, eastern region and South and Central America for FOR-A. “The first one will be the CS-HD1602 model with 16 inputs and two outputs. The ‘Clean Switches’ are HD routing switchers that do not create any video or audio glitch noise when switching the sources.”
This is important, Tanoue emphasizes, because the “Clean Switches” can be used as emergency back-up switchers when broadcasting.

Sony’s family of digital video routing switcher products offer simultaneous SD/ HD multi-format functionality in one frame, providing users with options that not only meet their present production requirements but also enable a simple and cost-effective upgrade path.
The key products in the line-up include four multi-bit-rate router frames: the HDSX5800, a matrix configurable up to 264x272 and expandable to 1024x1024; and the HDSX3700, 3600, and 3400 matrices, which are respectively configurable up to 128x128, 64x64, and 16x16. An array of highly configurable router control panel options is available, and remote control of Sony routers via the Internet is available through the BKSRNet control software.
The Sony production switcher’s matrix exists within the routers’ virtual space, allowing seamless control over all buses from all control surfaces. Memory recalls from switchers can control multiple router buses simultaneously.
“These products allow customers to have complete realtime control of signals within their digital video production environments,” said Paul Greene, product manager for production systems products, Sony Electronics’ Broadcast and Production Systems division. “Equally important, these tools can easily grow with an operation, expanding to meet and exceed a customer’s requirements.”
In addition to multi-format functionality, Sony routing products offer true realtime system control of up to 64,000 devices, with router programming able to be changed during router operations without interruption.
Tie-line management allows programmable tie-line trunks to automatically route signals through multiple levels of the routing system, while automatically establishing the routing paths between routers, including external Sony or non-Sony devices.
Using redundant CPUs, the Sony system can control large matrices up to 4093x4093, and multiple primary stations ensure redundancy and fail-safe operations. Primary stations and sub nets can be connected via Ethernet LAN as well as Sony’s proprietary S-Bus technology.
The UTAH-400 is the latest in digital routing from Utah Scientific. Features include “hot” redundant cross point cards that automatically activate, instantaneously and error free, if a failure occurs. The UTAH-400 offers signal presence detection on all router inputs and outputs, allowing monitoring of all critical signal paths feeding and leaving the router.
Other benefits within the UTAH-400 are internal analog video conversion and SDI and HD data rates all within the same frame. The various formats are added by simply installing the appropriate input and/or output card. The internal analog conversion eliminates the need for external conversion devices or tie lines between analog and SDI digital routers.
Two frames sizes are available for the UTAH-400, the 64x64 (4RU) or 144x144 (8RU), with the 144 frame being expandable to 1152x1152. The architecture of the UTAH-400 allows expansion on an 8 input or 8 output basis. This extremely small block size makes expansion very affordable and the flexibility of the router makes it simple to add whatever format is required.
Another strength of the UTAH-400 is its extremely low power consumption, with a fully loaded 144x144 frame consuming a meager 35W. Low-power usage results in lower operating temperatures, which in turn increases the reliability and life expectancy of the equipment.
“The UTAH-400 is taking the router market by storm, with deliveries of video and audio versions being made to customers in post production, newsgathering, television stations and network applications,” said Utah Scientific director of sales Ray Fowler.
